概括
这项研究发现,外部负载变量如总距离和加速度与青少年足球运动员在训练和比赛中的感知力度密切相关. 然而,健康指标显示出与外部负担的联系较弱.
科学领域:
- 运动科学
- 运动生理学
- 青少年足球表现
背景情况:
- 了解外部负荷和内部负荷之间的关系对于优化青少年运动员的训练至关重要.
- 感知劳动力 (RPE) 和会议-RPE (s-RPE) 是监测训练强度的常见指标.
- 全球定位系统 (GPS) 技术提供了EL的客观测量.
研究的目的:
- 检查U15,U17和U19男性青年足球运动员的EL和内部负载之间的关系.
- 确定最能预测年轻足球运动员的RPE和s-RPE的GPS衍生变量.
- 为了区分训练和比赛之间的关系.
主要方法:
- 在11周的赛季期间,从50名青年足球运动员收集的数据.
- 总共有1386次观察,包括145次训练和33场比赛.
- 使用GPS衍生变量用于EL和RPE/s-RPE的内部负载.
主要成果:
- 在所有年龄组 (U15-U19) 训练期间发现了EL体积变量和s-RPE之间的中度至非常强的相关性.
- 在训练中,总距离,加速,减速和球员负载是s-RPE最强的预测因素.
- 在所有年龄组的匹配过程中,总距离与s-RPE的相关性中等至大.
- RPE和s-RPE受到总距离,加速度,减速以及每分钟各种特定速度运行指标的显著影响.
结论:
- 目标EL测量,特别是与运动量和强度 (例如,总距离,加速/减速) 相关的测量,是青少年足球运动感知的可靠指标.
- 这些发现可以为教练监测训练负载和防止年轻运动员过度训练提供信息.
- 感知健康指标在预测该队列的外部负载方面具有有限的效用.

01:25Multiple Regression
3.2K
Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...
